Motorists were today promised disruptive roadworks would be finished on time.

Residents and commuters have faced a daily nightmare since the major reconstruction works on Cargo Fleet Lane began in January.

Some traders, who say they have been badly hit by the roadworks, said they understood the project was behind schedule.

But today, as workers prepared to start on the next stage of the scheme, Middlesbrough Council insisted the works would be completed on time despite delays caused by problems with water, electric and gas services.

A spokesman for the authority, which is carrying out the work with contractors Balfour Beatty, said: "It's a major project which cannot be avoided and cannot be delayed.

"We are sorry that it does mean disruption for residents, businesses and road users.

"However, we are on target to finish at the end of April.

"As does often happen in a project this size some parts have taken longer than first anticipated.

"We know that businesses are concerned but we have an open door and are ready to talk to them and be as supportive as we can."

Traffic has been avoiding the area since work began which has impacted on traders who rely on passing trade.
